The RealSSD C400 represents a mild performance gain over last year's C300 during light workloads, it's handily dispatched by competing drives from OCZ and Intel when it comes to heavy multitasking, but that's okay if the C400's price reflects its inferior performance and it does -- there's nothing wrong with delivering an entry-level product.

Expert reviews and ratings

So, have we seen a repeat performance of the RealSSD C300's grand entrance? Not really. Although we found the m4 to be considerably faster in our file transfer tests as Crucial fine-tuned top end sequential performance, that had little impact on our...

Crucial is a name we always know for reliability and quality-made products and the M4 drive is no exception. It is very well made and besides the controller everything else inside is made by Crucial (Micron). Crucial does offer their standard 3 year...

The performance of the m4 is rather interesting. The drive's random write speed is able to compete against SandForce drives but its random read speed falls behind the competitor. Its sequential read is faster and competitive yet the sequential write...

Finishing the review of the Crucial M4 SSD we can say that this drive has only given us positive feedback. "Starting with the out of the box performance and finishing with the latest firmware update that adds 70MB/S to the read speed. Also another...

Hand on heart, you know that drives with the latest SandForce SF-2200 series controller are probably the quickest you can buy. Is there any point in looking elsewhere? Well, yes. Price and reliability also come into the equation. Enter the Crucial M4...

When we reviewed the Kingston Hyper X earlier in the month we found it to be an absolutely blistering performer with a suitably enthusiast price-tag. The Crucial M4 is obviously cheaper in this 128GB guise, but also crucially (ahem) in the 256GB...

Crucial's m4 256GB solid state drive is a little gem. It can supply very fast read and write transfer rates, and it will noticeably boost the performance of a laptop or desktop PC when it's used as a system drive. Sure, it's quite expensive,...

Consumers looking to purchase a high-end SSD upgrade are likely to make their choice based on three criteria; performance, capacity and price. Based on those key factors, we've seen few SATA 6Gbps drives as compelling as Crucial's 128GB m4 SSD. ...

Although it's not radically different from last year’s model, the M4 is significantly faster than the disk it replaces. Intel’s 510 Series SSDs are still dominant in our performance benchmarks, but both have the potential to be blown...

The M4, despite its rebranding, is only a minor update to the C300. Despite the slightly updated and re-tuned controller, the additional sequential read and write performance has come at the cost of random read and write performance. The M4 is a very...

As for this specific 256GB Crucial model, £360 may still be a bit pricey for some but if you’re not a particularly data heavy laptop user or your system can accept some spinning platters for secondary storage, then I’d highly recommend...

The Crucial M4 has significantly increased the performance gap between it and the previous generation of SSDs. And by pushing write performance - for video capture and editing, graphical imaging, etc - the M4 provides an economical option for...

Compared to the older C300, Crucial's m4 SSD is more of a shift in performance priorities than a new design with improved performance all across the board. We see substantially improved performance in scenarios like Large File Copy and Game...

At first blush, the Crucial m4 seems virtually indistinguishable from its predecessor, the Crucial RealSSD C300. After all, it’s available in the same capacity with the same Marvell 9174 6Gb/s SATA controller and same amount of DRAM...
